mdd1, very interesting. I googled Daniil Galickij. This is the confusion I mentioned:
They were “Rutenian”. This has nothing to do with modern “Russia”. Google “Moscow” – and see that Moscow kingdom started way after that and it will take centuries until it will get to western places, primarily through Ukrainian Khmelnitsky who rebelled against Poles (and Jews) and tried to “partner” with Moscovites and got rolled over, of course. After that, Russia went to fight Turkey and small nations to take over Crimea and other places in the South. At the end of WW2, Soviets expelled Crimean Tatars to the Gulag (with huge life loss, as usual), and populated it with Russian peasants. These re-populated peasants are now the “natives” that Russia is “protecting”. Please add this piece of history to your puzzle.
For Polish _Lwow_ itself, 100 years ago, 20% of the city belonged to Ukrainian Catholics, 30% Jews, rest – Poles. 85% spoke Polish, 10% Ruthenian. This was typical for cities at that time – Poles and Jews were in the cities. Possibly, peasants around were more Ruthenian.
